title: [Analysis of misdiagnosis and differential diagnosis of infectious mononucleosis in adults].
abstract: OBJECTIVE
  To explore the clinical characteristics of infectious mononucleosis (IM) in adults.
  
  
  METHODS
  Medical records of 50 adult IM patients admitted in hospital were analyzed retrospectively.
  
  
  RESULTS
  Diagnosis delayed group contained 16 patients (32% of total patients) and was significantly different from the diagnosis in-time group in typical symptoms, signs and laboratory findings of IM.
  
  
  CONCLUSIONS
  The clinical manifestations of adult IM are rather complicated and nonspecific to diagnosis. History collection and physical examination in detail are helpful for early diagnosis.
